What is the general meaning of evolution?
Answer and explanation
Correct answer: Gradual change in organisms over time
Evolution is the gradual change in the inherited characteristics of populations over many generations. Small variations may accumulate, and helpful traits can become more common when they improve survival or reproduction. Therefore, option A correctly describes evolution. Option B is not a biological definition because a new organism does not normally arise in one day; options C and D are life processes, not evolutionary change.
